You should just draw one force at 7 degrees to the horizontal and then start the next one at74 degrees from where the first force stopped. And then connect the two ends together.
Which part of the last question?

I did like a parallelogram , Is that wrong??

No it isn't. There's the triangle way and the parallelogram way, so you're prolly right dw

No, 30 is correct. I thought since the gradient of the graph was negative it must be negative.

Yeah I think it is negative cuz the line was going downward , wish I had that much sense in the exam

Oh ok , what did u get for the magnitude and the direction ?

thanx man!
the very last Q of the paper. the young modulus one
6. There was one about calculations too , I cant remember , does anyone of u remember?
And yeah, what did u guys put for the last last mcq in which there were graphs they told the info like the object had constant resultant force , so which graph did u guys mark?

It is positive 7.5

what did you get?? i got 30.8 i forgot the angle tho
9. (Original post by examhater44)
It is positive 7.5
wait how did u get positive , can u explain ur method please
10. (Original post by examhater44)
what did you get?? i got 30.8 i forgot the angle tho
huh?? I got 33.5 I think
11. (Original post by shahida sulaiman)
huh?? I got 33.5 I think
They probably have a range cuz i know some people who got around 29 and 30....what did other people get so we can see the range??
12. what do you guys think the grade boundaries will be for an A?? I think 53-54
13. You are right actually it is negative, i made a stupid mistake

That is high I think, cuz paper in jan only had like 2 questions that were hard but this paper had like almost four questions hard

Lol even I got it wrong so no worries

That is nice to hear I am worried tho....I lost like 12 marks in the fly q and like 2 mcqs. everthing else felt very good so im hoping that i can get that A

I lost many marks in the last Q and am now just hoping that the grade boundaries be lower

i got the gradient question correct.. my magnitude was 28/29.. u think that will be wrong? and how do we take the angle?
i hope the grade boundaries will be lower...

I got 33.5 , I think urs might be right , idk about mine cuz its like far not between 30 or 28
My direction was like 16 , I think its wrong cuz I divided the angle by 2 and did cosine instead of tan but my parallelogram was drawn in such a way that I used cos instead of tan , what did u get for direction?

woah.. i dont remember exactly but not around a 16... i used a different method.. not the parallelogram.. how do we do the flea question? i mean the energy.. i wasnt able to do it that well
